To all whom it may concern:

Be it known that I, VICTOR IV. PAG, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the coun-ty and State of New York, have invented a new and improved Packing for Engine Crank Cases, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in internal combustion motors and it pertains more particularly to a crank case construction therefor.

Motors as commonly constructed are provided with a crank case, the lower portion of which forms the oil sump and is, removable therefrom in order that access to the crank shaft and its various co-ordinating elements may be obtained, and the present invention pertains more particularly to a packing means preventing the splashing of lubricant contained within the lower crank case or oil sump passing therefrom.

It is an object of the invention to construct a packing of vthis type from metal, and so position the same with respect to the lower crank case or oil sump that said lower crank case will automatically engage the packing when said lower crank case is positioned on the motor.

IVith the above and other objects in view, reference is had to the accompanying drawings, in which- Figure 1 is a detail longitudinal sectional view of a portion of an internal combustion motor, the lower or sump portion of the crank case of which is constructed lin accordance with the present invention;

Fig. 2 is a transverse detail sectional view taken on the line 2-2 of Fig. 1. y

Referring more particularly to the drawings, the reference character 5 designates the crank shaft, and 6 designates the rear ond thereof. This crank shaft is supported by main bearings and the reference character 7 designates the rear main bearinoof the motor, which bearing is mounted in the bearing 8 in the ycrank case 9 supported on the chassis 4 by ball supports as is usual.

The reference character 9 designates the lower crank case structure or oil sump, and 10 designates the clutch or iy wheel housing. This lower crank case or oil sump 9 is provided with a horizontally-disposed oil pan 11, suitablyA supported therein by shelves or shoulders 12 formed on the sides of the lower crank case or oil sump 9. The lower crank case or oil sump 9 is secured in position by means of bolts o-r the like 15 in the ordinary manner.

The lower part of the bea-ring 8 is spaced with respect lto the lower crank l'case or oil sump 9 and interposed within the space between said bearing 8 and the end` of the lower crank case or oil sump 9, is a packing member 16. This packingmember 16 comprises a metallic stripsecured to thebear-` ing 8, by means of screws or the like 17.

lower crank case or oil sump 9" is placed in v position and in moving the same to position .the inner top edge thereof engages the packing strip 16 and owing to the resilient nature thereof, said packing strip will pass inwardly of the oil crank case or oil sump to provide a tight 'joint therewith and to prevent oil splashing from the lower crank case or oil sump 9 into the clutch or ily wheel housing 10.

From the foregoing it is apparent that the Vpresent invention provides a new and novel form of effective seal between the lower crank caseor oil sump 9 rand the clutch and fly wheel housing 10, which packing is of such a nature as not to be disturbed byl removal and replacement of the lower crank casevor oil sump.

I claim- 1. In a crank case construction having a` removable lower portion and a bearing support, a packing strip, said packing strip being secured to said support so positioned as to frictionally engage the removable portion of the crank case, as and for the purpose set forth.

2. In an internal combustion motor, a main bearing support, a crank case having a removable lower portion, and a packing carried by the bearing support and adapted i for frictional engagement with the remo-vable crank case portion, as and for the purpose set forth.

3. In an internal combustion motor, a

main bearing support, la crank voase having a rel'ofble 'lower portion, and '21, packing Comprising' a T'silent metal Strip prlanently secured to the main bearing support and adapted for engage-ment with `the" te# movable crank oase portion, as and for' the purpose se-t fort-11.`
